Could fasting with vitamin c help reduce the chances for loose skin issues?
There are anecdotes that fasting helps with loose skin more than other types of dieting. Jason Fung I believe promotes this, but he’s… not well respected in the scientific community.
I believe gotu kola was promoted by Charles Poliquin (rip) and this is talked about on Mark Bell’s old powercast. There’s two episodes irc so you’ll have to skim through them. No idea if it works, but it’s the only supplement I recall hearing about working for that.
